@Gerd, @darkeye I have forked and built the Day Scope now using the original launchpad version.
A click package which works for myself can be found with the changed code on my personal Github repo https://github.com/mharrend/ubuntu-touch-day-scope.
Unfortunately, the moon phase indication is not working any longer since an external API was used for this functionality which requires a fee-based license.
@darkeye Feel free to fork my repository to the official UBPorts repository.
Maybe, we could use another API provider for the moon phase like http://www.farmsense.net/api/astro-widgets/ or we should remove the moon phase indication.
